Abstract (en)

[origin: WO2010083166A2] Example in-situ stress measurements in hydrocarbon bearing shales are disclosed. A disclosed example method includes lowering a downhole tool into a wellbore penetrating a subterranean shale formation, logging via the downhole tool, a portion of the wellbore adjacent the shale formation to generate logging results, processing the logging results to select test intervals along the portion of the wellbore, performing a stress test at one or more of the selected test intervals to generate stress test results for the shale formation, and adjusting a model representing at least one property of the shale formation based on the stress test results.
